TITLE: DR DOS 6.0 COMPATIBILITY WITH LANTASTIC NETWORK
DOCUMENT ID#: FYI-M-1406
DATE: 06NOV92
PRODUCT: LANtastic & DR DOS
PRODUCT VERSION: 4 & 6.0
SUPERSEDES: 13DEC91
ISSUE/PROBLEM
DR DOS 6.0 and LANtastic 4.0 have been tested together by both
Novell and Artisoft, and were found to be extensively compatible.
Customers with earlier versions of either DR DOS or LANtastic may
achieve partial functionality when running the two products
together. However, such functionality is coincidental and is not
supported by either Novell or Artisoft. Customers who have earlier
products and who experience problems should upgrade LANtastic or DR
DOS as necessary.
Testing of DR DOS 6.0 and LANtastic 4.0 revealed only a small
number of minorconfiguration issues, which are as follows:
1. SUPER PC-Kwik
Super PC-Kwik advanced disk reads and writes should be
disabled on LANtastic because the Super PC-Kwik scheduler
conflicts with the LANtastic scheduler causing machines to
hang. To avoid this problem on a machine running SERVER, use
the Super PC-Kwik switches /D- /H- to disable advanced disk
reads and writes. Normal caching is still active when these
switches are used.
Note that you do not need to disable advanced disk writes on
a node which is not running SERVER.
As is true of most server/cache combinations, Super PC-Kwik
cannot cache redirected network drives.
2. WINDOWS 3.0 IN ENHANCED MODE
To run Windows 3.0 in enhanced mode using the DR DOS 6.0
EMM386.SYS memory manager, customers need to use an Artisoft
LANTASTI.386 driver dated 08-16-91 or newer. Customers with
older LANTASTI.386 files can obtain a current driver from
Artisoft Technical Support.
3. LANPUP UTILITY
Network redirections work properly under DR DOS 6.0, however,
the LANPUP terminate and stay resident utility will not
display the redirection properly.
4. DR DOS 6.0 DISK UTILITIES
Certain DR DOS 6.0 disk utilities are intentionally designed
for use only on local drives and will return an error message
if run on a redirected (network) drive or on a machine running
the SERVER program. These utilities are summarized below:
Utility On SERVER? On network drive?
------- ---------- -----------------
CHKDSK N N
DELPURGE N N
DELWATCH N N
DISKMAP Y N
DISKOPT N N
FDISK N N
FORMAT Y N
PASSWORD Y* N
RECOVER N N
UNDELETE Y N
UNFORMAT N N
* Files on a server protected by PASSWORD cannot be accessed
from LAN workstations, even when the correct password is
provided. They may, however, be accessed at the server on its
own physical drive.
5. SUPERSTOR
One LANtastic 4.0 test system was run with a DR DOS 6.0 server
whose hard drive had been prepared using the SuperSTOR disk
compression utility. All nodes on the network, even non-DR
DOS nodes, could access data on the SuperSTOR drive. Efforts
were made to exercise the test system heavily, however
customers should consider use of SuperSTOR partitions on
LANtastic servers as "at their own risk" at the current time
and use standard precautions such as frequent backups of
essential data. We also strongly recommend that customers
read DR DOS Technical Tip # 1200 before creating or using a
SuperSTOR drive.
6. RARE QUICKBASIC PROBLEM
The initial shipments of DR DOS 6.0 had a rare problem in
which server pathing was not handled correctly by a Microsoft
Quickbasic application under LANtastic 4.0. This problem was
reported by only a single user in the field and was very
difficult to reproduce even in our testing laboratories so is
unlikely to be seen by most customers. The problem relates to
the "double backslash" \\ before the server name, and has been
corrected. Customers who see the problem, and who have DR DOS
files dated prior to 12/91, should contact Novell technical
support for updated files.
7. TASKMAX
LANtastic software should be loaded before TASKMAX is invoked.
This permits all TASKMAX task sessions to access the network.
8. INTERNATIONALIZATION ISSUES
(Country, Keyboard, Codepage, and Graftabl) The U.S. version
of LANtastic will run only with the default (U.S.) DR DOS 6.0
country and keyboard. DR DOS 6.0 customers who require
alternate country support, codepage, or graftabl support
should contact Artisoft for an international version of
LANtastic 4.0.
9. NET PRINT, NET EXPAND, & NET DIR
These commands will fail on DR DOS 6.0. Call the Lantastic
BBS (602-293-0065) for the patch called DRXCIP.EXE, a self
extracting archive file.
ADDITIONAL INFORMATION
Artisoft provides a similar but more extensive document on DR DOS
6.0 compatibility with LANtastic 4.0. This document, which details
the hardware and network cards tested, can be obtained from
Artisoft's technical support bulletin board at (602) 293-0065 or
from the Artisoft forum on CompuServe.
